As opposed to reference an issue, I want to just output the text #5 without any link. How can I do that?
For example, a shader error message from Unity could contain # and a followed
number:
Shader error in 'Nature/Terrain/Standard':
actual parameter #3 must be same type as formal out parameter ("weight")
actual parameter #4 must be same type as formal out parameter ("mixedDiffuse")
actual parameter #5 must be same type as formal out parameter ("mixedNormal")
too many parameters in function call at line 64 (on d3d9)
I have tried \#5 and #5 but they don't work: still linked.
The question doesn't focus on how to escape #, but #5, which will be translated to a link to another issue. That's unexpected.
You could put an invisible character between the # and the number.
e.g.
#​5 will be rendered as #5 on GitHub.
​ being the unicode "zero width space" character.
